Can you really start a fire with a solar survival lighter?
While he has tested some interesting products in the past, these solar fire starters may be some of the most unique, harnessing the power of our closest star: the sun!
Reminds you of using a magnifying glass to burn things as a kid, doesn't it? And it actually works in a pretty similar fashion, simply by focusing the sun's rays to a combustible piece of material.
The biggest drawback is that a cloudy day can render these things worthless. When facing a survival situation, that could be problematic.
But these devices do look small and light, which could save quite a bit of space in a crowded pack. It really all depends on your level of patience and personal preference in the end.
